1.一个人总要走陌生的路，看陌生的风景，听陌生的歌，然后在某个不经意的瞬间，你会发现，原本是费尽心机想要忘记的事情真的就那么忘记了。 1.One is always on a strange road, watching strange scenery and listeningto strange music. Then one day, you will find that the things you tryhard to forget are already gone.
2.幸福，不是长生不老，不是大鱼大肉，不是权倾朝野。幸福是每一个微小的生活愿望达成。当你想吃的时候有得吃，想被爱的时候有人来爱你。 2.Happiness is not about being immortal nor having food or rights inone's hand. It’s about having each tiny wish come true, or havingsomething to eat when you are hungry or having someone's love when youneed love.
